Walker, looking for an AFC East position group that could “exceed preseason expectations,” thinks the Dolphins quarterbacks have a chance to surprise in 2012.

“The Miami Dolphins are the only AFC East team without a clear-cut starter at quarterback,” Walker writes. “But they own the deepest group of quarterbacks in the division — and possibly the entire NFL.”

In terms of finding a franchise quarterback, “the next Marino” if you must, the team will look to continue to develop Tannehill. Collectively, though, it’s as solid as any Dolphins quarterback group has been in the past decade. What’s different about this group? There’s no overlap, each player has a different skill set that translates differently and successfully.

“Matt Moore, David Garrard and rookie first-round pick Ryan Tannehill all bring something to the table,” Walker writes. “Moore is coming off a career year and is a gamer. He won six of his last nine starts in 2011. Garrard has tons of experience and is a former Pro Bowler who has won in the playoffs. Tannehill has a ton of potential and can make all the throws. The rookie is Miami’s quarterback of the future.”
